Scope: Test 1A - This test is for evaluating the colorfastness of textiles that expected to withstand repeated hand laundering at low temperature. Specimens subjected to this test should show color change similar to that produced by five typical careful hand launderings at a temperature of 40 ± 3°C (105 ± 5°F).

Sample is paired with a multi-fiber strip

Then placed in a launder-o-meter and accelerated hand laundering is performed with a detergent solution

Color change of the sample and staining of the multi-fiber stripe is evaluated

Scope: Test 2A - This test is for evaluating the colorfastness to washing of textiles that expected to withstand repeated low temperature machine laundering in the home or in the commercial laundry. Specimens subjected to this test should show color change similar to that produced by five commercial launderings at 38 ± 3°C (100 ± 5°F) or by five home launderings at medium or warm setting in the temperature range of 38 ± 3°C (100 ± 5°F).

Sample is paired with a multi-fiber stripe

Then placed in a launder-o-meter and accelerated machine laundering is performed with a detergent solution

Color change of the sample and staining of the multi-fiber stripe is evaluated
